The origin of polyhedral D&D dice
I didn't know this. From an interview with Gygax:
Q. As far as you know, what was the basic evolution of polyhedral dice? If they existed prior to the creation of Dungeons & Dragons, what were they used for?To the best of my knowledge I introduced them to gaming, en masse, with D&D in 1974. I found sets of the five platonic solids for sale in a school supply catalog back in 1972, and of course ordered them, used them in creating the D&D game.

Googling "divinity dice" reveals some talk about using platonic solid dice for purposes of divination, but that's different than for gaming.
Apparently, the Romans did use 20-sided dice for gaming. So Gygax can't claim to be entirely original. Dungeons & Dragons and its descendants are certainly responsible for their modern popularity.
I need to find the ancient source for this "dice of the gods" turn of phrase though.
